To put it simply, because of the way the windows filter-manager positioned the legacy filter drivers in relation to the newer "minifilter" drivers, data did not flow through the filter driver stack in the proper order. As a result SEE-RS did not function as expected.
Symantec was able to determine that use of a "null" or "dummy" legacy filter driver would force Windows filter-manager to split the filter stack frames so that data would flow through the filter-stack properly.
To determine if you are experiencing this issue:
Open a Windows command prompt and use the "fltmc" command.
Look at the "Altitude" column. This column should be in descending numerical order. (This example shows an improper Altitude column. Drivers ordered in this way will result in the error behavior)
If the altitude column is not in descending numerical order please contact SEE-RS support to investigate and determine the best solution.
